Domain and Range Examples: Easy
1) To see pictures bigger click on them
The domain is (-∞,∞) The range is [2,∞)
Because you the graph goes on forever into the x-values and the y-value it is a ( or ) around the ∞ and because the 2 is a definite point and we know for sure that the graph and theres it is a [ around it.

2)
The domain is [0,∞) The range is [0,∞)
Because the graph starts at (0,0) both the domain and range have that as their first point and since the graph goes on forever up and to the right both the domain and range have ∞ as their second point.
